How to maintain and maintain the server room cabinet

The computer room environment has an important impact on the normal operation of the server. Therefore, the first part of server maintenance and maintenance is to do a good job in the construction of the computer room environment. The computer room should ensure sufficient space for the installation and configuration of server related equipment, and the partition and floor of the computer room should be treated with details such as anti-static.

The fire prevention work of the computer room is also very important, and it is necessary to do a good job of fire prevention treatment for walls and cables. In the event of a fire, how to ensure the safety of the equipment and how to ensure the orderly evacuation of personnel are all factors that need to be considered in the construction of the computer room. The temperature and humidity of the computer room should also be controlled within a certain range, and the temperature and humidity have a great impact on the normal operation of electronic products.

A server is an electronic device that is sensitive to both temperature and humidity. If the server is located in a computer room that is too dry, it is very easy for personnel to generate static electricity during contact with equipment in the computer room. This kind of static electricity generally has thousands of volts or even tens of thousands of volts, which is very dangerous for the normal operation of the server and can easily cause serious accidents.

How to do a good job in the layout and management of the computer room scientifically and reasonably is the key to the construction of the computer room. At present, there are still many places that need to be improved in the management of computer server rooms in China, such as the modernization level of computer room management is not high, and many monitoring and maintenance work is still completed solely by manpower, and there is no information and network management mechanism. In fact, the electronic detection system is not much difficult in terms of design or implementation, but due to our lack of attention, the overall level of computer room construction is still hovering at a low level.

Proper maintenance of network cabinets is very important to prolong the service life of network cabinets. How to maintain the following points:

1. Maintain the network cabinet at least once a month, and make maintenance records.

2. The gears of the network cabinet are prone to dust, and the gears should be cleaned during maintenance to ensure that the gears are kept clean.

3. Check whether there is any deviation in the gap between the teeth at the perforated part of the network cabinet and adjust it.

4. Clean up the pollution on the surface of the cabinet in time to prevent the oil, dust, acid, alkali and other local pollution attached to the surface from corroding the cabinet. Try not to clean the cabinet, just wipe it with a slightly damp cloth.

5. Regularly inspect the surface of the cabinet to prevent scratches on the surface of the cabinet, resulting in the destruction of the passivation film and the rust of the cabinet. Because the network cabinet is made of metal, if it rusts, it will reduce the service life of the cabinet, even if it does not affect the use.

Space control, the space control of the server is mainly for easy planning and management, and there is a small reason for the temperature control mentioned above to achieve better heat dissipation. The messy placement of the server or the display of network cables everywhere, only from the direct sense of vision, there will be a sense of boredom that can't be reasoned, and when you guess which server or what part of the server has a problem, it is more troublesome to deal with it, and a good spike car sliding space control is also very good for temperature control, just like a network cable, a bunch of network cables are placed messily behind the cabinet, which will block the air flow of the server below, and the temperature will grow steadily. If SailXun is a tower server against the wall in a small computer room, it is advisable to make full use of the space, strive to maintain temperature control, maintain power supply and KVM and other daily maintenance, and the body should be about 12cm away from the wall.

We have the easiest way to answer for you, you have to solve the problem according to your own way of self-indulgence, give the answer that is reasonable, you have been bright and clear to ask the question of the relevant content has been prepared to ask you the answer in a non-reasonable way.

1. Daily maintenance plan.

The maintenance items are as follows:

1) The network administrator conducts routine daily inspections of the computer room and fills in the "Registration Form for Environmental Inspection of the Central Computer Room" in detail.

2) Clean the floor, cabinet and server surface of the computer room every Tuesday afternoon.

3) Dust the server thoroughly on the fourth Tuesday of each month.

4) Inspect the air conditioner to confirm whether it is in good working condition and whether the drainage pipe is smooth.

5) **High-end machine, network switch dust removal, and ensure that it is in good working condition.

6) Clean the cabinet and patch panel to ensure that they are in good contact.

7) Check whether the UPS is in good working condition and whether the charge and discharge are good.

8) Check the tightness of the access control in the computer room, and report and solve any problems in time.

2. Quarterly maintenance plan.

The specific maintenance time is the last week of the end of each quarter, and the maintenance items are as follows:

1) Thoroughly clean the interior of the machine room and the surrounding environment.

2) Dust all equipment in the computer room.

3) Check and clean the air conditioning system.

4) Charging and discharging operation of UPS system.

5) Check the working condition of the equipment and power supply, and make a record.

6) Charge and discharge the UPS.

7) Check all kinds of safety, fire prevention and alarm equipment during the change of seasons.

8) Check the waterproofing and lightning protection measures in the computer room, and make a record.

3. Other maintenance plans.

1) Inspection and dust removal of temporary additional equipment.

2) The computer room will be repaired in two years, and the equipment and equipment of the computer room will be carried out according to the actual situation, and the time will be selected as the year.

3) Five years, overhaul the equipment and computer room (the time is selected as the year).

1.Set a reasonable dust collection cycle.

Set a reasonable dust removal cycle according to the specific conditions of the computer room, and clean the inside of the computer room, the outside of the computer room, and the inside of the equipment in the computer room. Taking a medium-sized computer room as an example, the internal hygiene of the computer room should be cleaned every three days and thoroughly cleaned every half month. The external sanitation of the computer room should be cleaned every day, the dust adsorption of the equipment should be checked every week, and the equipment that needs to be cleaned should be cleaned once a month. Repair the equipment and room of the computer room every two years according to the actual usage; The computer room and equipment are overhauled every five years.

2.Beware of static electricity hazards.

When disassembling and cleaning the equipment, the first thing to avoid damage to the equipment caused by live personnel is avoided. Before cleaning, you should wear anti-static clothing, wear anti-static rings and other equipment. Avoid live disassembly, which must be done with a complete power outage and a well-grounded server, even for hot-swappable devices, to prevent damage to the device caused by static electricity.

For devices such as displays, discharge treatment should be done first.

3.Understand the structure of the device.

Since the equipment in the computer room comes from different manufacturers, the design of each is not the same, especially the design of many brands of server chassis is special, which requires special tools or mechanisms to open, when removing the chassis cover, you need to read the manual carefully, do not forcibly disassemble.

4.Select the cleaning tool.

The cleaning of the equipment does not require complicated tools, and the general dust removal maintenance only requires the preparation of a Phillips screwdriver, a flat screwdriver, a paint brush or an oil paintbrush. Hair dryers, anhydrous alcohol, heat dissipation silicone oil, absorbent cotton balls, clock drivers, tweezers, and leather tigers are also essential tools. If simple maintenance is required, equipment such as needle-nose pliers, voltage testers, and multimeters are also required.

Note: Do not use brushes that are easy to remove hair, such as ordinary brushes, otherwise it is easy to damage the machine. Special attention should be paid to the dust removal of the power supply.

1) Organize a suitable operation and maintenance team: need to be able to handle electricity, air conditioning, network, security, fire protection equipment, etc. 2) Make regular maintenance plans: plan by day, month, quarter and year, including what needs to be done by yourself and manufacturers 3) Implement maintenance and deal with faults

Do a good job of fault handling plan, regular training or simulation of fault to improve the ability If the maintenance plan will not be done, find various manufacturers to come and discuss.

The maintenance plan needs to have three elements: 1, maintenance regulations, 2Implementation process, 3Record templates.

In a nutshell:

1. Maintain the power support system, regularly and irregularly inspect the line, stabilized power cabinet, etc.

2. Maintain communication infrastructure, routers, network cables, switches, etc., and pay attention to lightning protection.

3. It is difficult to maintain the software support system in one word, in short, it is necessary to keep it optimized at any time.

1.Preparation.

First of all, the user should be notified to organize the cabinet without affecting the normal operation of the user.

Then, according to various factors such as the topology of the network, the existing equipment, the number of users, and the user group, the wiring diagram and the equipment location diagram inside the cabinet are outlined.

Next, prepare the required materials: network patch cords, label paper, various types of plastic cable ties (strangled dogs).

2.Organize the cabinets.

Installing the cabinet: You need to do the following three things by yourself: first, use the screws and nuts of the random frame strap to tighten the fixing frame; Second, pull the cabinet down and put the movable wheels on; Thirdly, adjust and add baffles to the mounting frame according to the position of the equipment.

Group network cables, and the number of groups is usually less than or equal to the number of cable management racks behind the cabinet. Tie the power cords of all the devices together, insert the plugs through the cable holes at the back, and look for the respective devices through a separate cable management frame.

Secure equipment: Adjust the bezels in the cabinet to the appropriate position so that the administrator can see the operation of all equipment without opening the cabinet door, and add the bezel as appropriate for the number and size of the equipment. Be careful to leave a certain amount of space between the baffles.

Place all the switching equipment and routing equipment used in the cabinet according to the pre-drawn diagram.

Labeling of network cables: After all network cables are connected, it is necessary to identify each network cable, wrap the prepared sticky notes around the network cable, and mark them with a pen (generally indicate the room number or what it is used for), and the logo is required to be simple and easy to understand. Crossover cables can be distinguished from regular cables by using sticky notes of different colors.

If there are too many devices, the devices are classified and numbered, and the devices are labeled.

3.Post-work.

UMC Test: After confirming that everything is correct, the power supply is turned on and the network connection test is carried out to ensure that the user is working normally - this is the most important thing.

The number of the equipment and the identification of the network cable should be indicated on the diagram for maintenance and reference. It would be a good idea to include the username as a part of the icon. Finally date and informant.

Basic requirements for maintenance services:

1. Equipment maintenance service requires 7 (days) 24 (hours) and 4 (hours) to respond to on-site service, and the replacement parts provided are not lower than the performance of the original accessories.

2. For server hardware failures that cannot be solved within 24 hours, provide server standby support, and provide standby performance and grade not lower than faulty servers.

3. Provide on-site support services. The contents include: system installation, upgrade, daily maintenance; Hardware fault judgment and repair; On-site hardware services. After all services are completed, the service work report shall be provided and signed by Party A.

4. Regular inspection once a month. Detect the hardware operation, formulate the inspection plan, and provide the system test report and detailed analysis report after the inspection is completed.

5. It is best to use the MPO MTP optical fiber strip line, ODF optical fiber distribution frame, optical fiber terminal box and so on in the computer room data center, and it is recommended to use Phoenix, which is super cost-effective.
